Abstract

PURPOSE:To freely set temperatures on the upper half of a body and the lower half of a body by providing a temperature determining unit for calculating temperatures of the upper and lower halves of a body from the temperature on the lower half set by a temperature adjusting knob and the feeling of the upper half of the body. CONSTITUTION:A controller 7 calculates a set temperature of a first heat generating body 2 from a scale set by a temperature adjusting knob 8, and if an input sensation is 'hot', 'medium' or 'lukewarm', set temperature of a second heat generating body 3 is calculated according to the set temperature of the first heat generating body 2. Then, the temperature of the lower half of a body is detected and amount of power to be supplied to the first heating body 2 is calculated to control the amount of power supplied to the first heat generating body 2. Then, the temperature of the upper half of the body is detected to calculate the amount of power to be supplied to the second heat generating body 3 to control the amount supplied to the second heat generating body 3. With this constitution, if a user sets a scale for the lower half of the body with the temperature adjusting knob 8 and inputs a desired feeling of the upper half of the body from a feeling input switch, the temperature of a whole body corresponding to the feeling of the user can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a heating cloth that is comfortable for the user and allows a comfortable sleep.

[Prior Art] FIG. 7 is a wiring diagram of a heating element of a conventional heating cloth as shown in Japanese Utility Model Application Publication No. 59-4554.

This heating cloth will be explained below in Figure 7. (1) is a cloth in which heating wires can be wired, for example, a blanket, and (2) is a cloth that is spaced at the same intervals throughout almost the entire blanket (1). The heating element A, (3) is wired in a meandering manner along the heating element A, and the heating element B, (4), (5) is partially wired at a predetermined location of the blanket (1) that is placed at the feet during heating. ), <6> are the main body plug, connector and main body side cord, (7
〉 is a controller that has a built-in temperature control circuit for heating element A (2) and heating element B (3), and is equipped with a switch (not shown) for switching the energization to the heating element (2〉(3)〉). By operating the knob (8>), both heating element A (2) and heating element B (3) are energized;
A state in which only heating element A (2> is energized) and heating element B (3)
It is configured such that it can be arbitrarily switched to a state in which only the current is energized. (9> is the power supply side cord, and (10) is the power plug.

A specific usage example for the above configuration will be explained below. When the entire body is heated (both heating element A (2) and heating element B (3) are energized), the foot area is heated by heating element B (3). A high temperature can be obtained by adding electricity, and if only heating element A (2) is energized, the entire body is heated uniformly, and if only heating element B (3) is energized, only the feet can be heated.

1. Problems to be Solved by the Invention] A person's sensations in bed differ depending on the body part. 6th
The figure shows the results of a sensory experiment using an electric blanket, showing the temperature and thermal sensation of the blanket on the shoulders and feet. "
Thermal sensations such as "hot" and "cold J" usually have thresholds on the low and high temperature sides, and there is a large change in sensation on the low and high temperature sides of this threshold, and there is also a temperature neutral range surrounded by the thresholds. Then, the change in sensation will be slight, and you will be in a state where you are neither hot nor cold.

From the experimental results, when comparing the shoulders (straight line) and the feet (broken line), it can be seen that the temperature neutral range has shifted to the higher temperature side for the feet than for the shoulders.

In other words, at the same temperature, the shoulders and feet experience different thermal sensations, so if the upper and lower body temperatures are set to the same temperature,
The problem was that it was difficult to get the same feeling.

In addition, the heating cloth shown in the conventional example requires setting the temperature for the upper body and lower body, respectively, and has the disadvantage that it is difficult for the user to set the temperature. Sensory experiments have shown that there are large individual differences in the threshold temperature for the low temperature side of the feet, and the comfortable range of foot temperature varies greatly from person to person. It turns out that it is difficult for users to set the temperature to their own preference.

The temperature of such heating cloths used during bedtime can only be adjusted until before falling asleep, so it is possible that the temperature may be adjusted incorrectly and remain uncomfortable until the morning.3 Therefore, it is important that the controller's operation section be easy to understand. .

This invention has been made to solve this problem, and is provided with a temperature determination unit that calculates the temperature of the upper body and lower body from the temperature of the lower body set with the temperature control knob and the sensation of the upper body. The purpose of this invention is to provide a warming cloth that allows the temperature of the upper and lower body parts to be freely set and is easy to operate.

[Means for Solving the Problems] The heating cloth according to the present invention includes a heating element wired in a meandering manner on the upper body side of the cloth and a heating element wired in a meandering manner on the lower body side of the cloth when warming the cloth, and the user can adjust the temperature according to his/her preference. It has a temperature determining section that calculates the set temperature of the heating elements wired to the upper and lower body parts by inputting sensations.

1 action] The heating cloth in this invention has two meandering wirings arranged in the heating cloth.
The temperature of the two heating elements for the lower body is determined by the scale of the temperature control knob, and for the upper body by the set temperature of the lower body heating element and sensory input from the upper body, so the temperature of the lower body, which has large individual differences, is determined. You can make detailed settings to provide a comfortable sleep environment.
